Clear information.
Clear boundaries.
Jail411 is an independent information resource for families and friends. We are not a government agency, jail operator, law firm or live custody-records service.
Can Jail411 tell me if someone is in custody right now?
No. Jail411 does not hold live custody records. Use the official locator for the county, state, federal or ICE system that has the person; start here if you do not know which.
Does posting bond mean the person comes home?
Not always. A probation or parole hold, another county's warrant or an immigration detainer can keep someone in custody after bond is posted. Ask the jail what holds are on the booking before you pay.
What should I confirm before visiting?
The person's current facility, the visiting schedule, approval requirements, accepted identification and arrival instructions. Check the facility page and its official sources before you travel.
What if I find something that needs correcting?
Send us the page and the detail that needs attention. Include the official source when you have one. Do not send private booking documents or other sensitive personal information.
